' noon Application filed. March 8,

The invention relates in the present embodiment'to locks of the latchbolt type having an axially slidablespindle for actuating the latchbolt, a knob'on one side ofthe door fixedly engaging the spindle and aknob on the other side of the door releasably 'en-' gaging said spindle.It will be noted that'in such type of lock, in the normal positionthereof both knobs engage the spindle wherem by it may be freelyoperable from either side of the door but upon a proper axialdisplacement of the spindle, the outer knob will be released fromoperative engagement with said spindle so that the latch bolt mayth'enonly be actuated from the outer side of the door, by key cont-rolledmeans associated with the outer knob.

One of the objects of the present invention is'to provide a lockof thecharacter described which is so designed that locks embodying thesamestructure and tumbler barrels may be used on a plurality of doorswithout at the same time entailing the disadvantage of having everykeyywhich may rotate all tumbler barrels likewise operate every lock. I

Another feature, or object, of the invention is to provide a lockof theclass described in which, upon the axial displacement of the spindle torelease the outer knob from operative engagement therewith, independentmeans will automatically function to lock the spindle in displacedposition whereby no amount of j arring will operate to release thespindle.

A further object of the invention is to provide a particularly effectivemeans of locking the outer knob against movement when the spindle hasbeen operatively disengaged therefrom. I

A still further object of the invention is to provide a lock of theclass described having a spindle of readily detachable portions wherebyportions of varying length maybe substituted to suit doors ofdifferingthicknesses without necessitating the dismantling of the lock.1 7

Yet another object of the invention is to" provide, in a lock of theclass described, a" 0 particularly efficient means for insuring the.-

, The invention possesses other objects'and features of advantage, someof which,fwith the foregoing, will be set. forth in the followingdescription of the preferred form ofthe invention which is illustratedin the drawings accompanying and forming part of the specification." Itis to be understoodyhowever, that variations in the showing'niade bythesaid drawings and description may be adopted within the scope of theinvention .as set forth in the claims.

Referring to said drawings, Figure 1 is a fragmentary plan section takenthrough the lock and a door on which the lock is mounted, thelatch boltcasin showing in plan and not in section. 0'

Figure 2 is a vertical-section of the "lock F igure 7 is' a viewsimilarto F igure 3 but showing the parts in different operative relation.

The present embodiment of my invention isincorporated in a lock 8disposed in 'a suitable cavity 9 provided in the free edgeportion llpo fthe door 12, and which is arranged to beoperated from the inner andouter sides of the door bymeans of knobs 13 an'dl.

The lock is provided with a bolt 16 which is arranged to normally extendfrom the outer end of a bolt casing 17 mounted in the door edge 11,

Slidably mounted in the casing 17 is a bolt yoke or latch plate member18 for actuating the bolt 16, such member being here shown hollow and ofgenerally rectangular outline and being urged to assume and maintain anouter position by reason of a spring 19 operatively engaged behind it. Journalled in the casing 17 to extend horizontally there through is alatch actuator 21 having extent ing therefrom intermediate the casingwalls 'an arm 22 arranged for engagement with the latch plate 18 in suchmanner that a rotation of the actuator from the normal position shown inFigure 2 will effect a retractive displacement of the latch plate.Preferably, and as shown, the actuator arm 22is arranged for engagementwith the latch plate both at upper and lower sides thereof whereby arotation of the actuator in either possible direction may retractthelatch plate.

Extending axially through the actuator is an'opening 23 arranged for theslidable re ception of the spindle 24, the opening and spindle being oflike polygonal section whereby rotation of the actuator may be effectedby rotating the spindle. Rotation of the spindle is arranged to beeffected by means of the inner and outer knobs 13 and 14, the former ofwhich is fixedly secured to the spindle by means of a screw 26 and isslidably and rotatably disposed in the escutcheon plate 27 positionedagainst the inner side of the door. V

The spindle extends through a cavity 28 of the door, which is combinedwith the cavity 9. Covering the cavity 28 and positioned against theinner and out-er surfaces of the door are side plates 29 and 31 whichsecure the lock in position. The plates are connected together by meansof screws '32 extending from the plate 29 and engaging insegmental-shaped arms 33 fixed to the plate 31. Asclearly shown inFigure 1, the plates are concealed within the inner escutcheon 27 and anouter escutcheon 34, the latter be ing interposed between the outersurface of the door and inner edge of the outer knob.

Preferably, and as will be more fully hereinafter explained, the spindleis, for the pur pose of-easily adapting the lock for doors ofdifi'erentthicknesses, formed of two sections 36 and 37 which'areconnected together by means of cooperating hook and eye members 38 and39 respectively formed on the sections, said members havinginterengaging sides to prevent relative rotation of the sections inattached position. Preferably detachably secured to the outer knob suchas by a bayonet connection and locked in such position by a member 41,is a knob sleeve42 which as here shown extends through the plate 31.Opere ative connection between the spindle and sleeve to permit rotationof the former by the outer knob is effected by means of a lug 43extending transversely from the spindle section 37 and arranged inprotracted or forward'position of thespindle to engage in a notch 44formed in the rear end of the sleeve. It will be evidentthat with thelug seated in the notch, as is the case in Figure 5, the outer knob maybe used to effect a retraction of the latch bolt, whereas when thespindle isv moved spring 46 which is interposed between a suit-,

able stop at the forward end of the spindle section 37 and a bearingwall 47 which is held against axial displacement in the sleeve but isfreely revoluble therein. The spindle ex tends through an opening 48 ofthe wall,

such opening being polygonal to conform to the cross-sectional shape ofthe section 39 wherebythe latter, while capable of rela-' tivelongitudinal movement through the wall, is fixed for rotative movementwith it.

Revolubly mounted within the outer knob casing and fixed to the bearingmember 47 for rotation therewith is what may be conveniently termed akey-tip receiving member 49 which is operatively aligned with andadjoins a tumbler barrel 51 held in theknob 14. The member 49is=provided in the forward end thereof with a kerf 52 which communicateswith the key passage 53 of the tumbler barrel'and is arranged to beengaged by the tip of a key adapted for insertion through said passage.Since the receiving member 49 is not displaced by the longitudinalmovement of the spindle, it will be evident that in the retractedposition of the spindle, rotation thereof from the outer side of thedoor to elfect a retraction of the latch bolt may be readily effected byturning the proper key in the tumbler with the key tip engaging in thekerf. In. Figure 9 I have shown the receiving member 49' provided with aslight change enough to operate a lock otherwise the same but having inplace of member 49., the member 49' which is provided with the kerf 54..On the other hand a key which is long enough for engagement with thekerf of a lock equipped with member 497 may also be used with lockshaving the receiving members 49,

here shown, the lug'i s arranged to ng ge the pawl during theretractive' movement of the spindle to prevent inwardmovement'of thepawl before the lug has moved past same. l/Vith the pawl thus-lockingthe spindle against forward movement, it will be clear that even whenthe door or looks are sub:

jeeted to violent jolts, the spindle will not be released to allowtheretraction of the bolt. by means of the outer knob, On the other handthe release oi: the spindle may be readily effected from the. inside ofthe door-by rotating the inner; knob wherebythe lug rwill be moved fromengagement :Vllll'l the pawl,

By forming thesections esp mate, as particularly shown-here," the only variation inthe lock necessary to accommodate different door thicknesses is thevariationxin the length of the spindle section 36' be disposed normaland the change in the position of the slide to retain the'properrelationship with the latch yoke 18.
